Sight flow transmitter | clear polycarbonate cover.

Series SF Sight Flow Transmitter

±2% FS Accuracy, 4 to 20 mA Output, Pressure up to 500 psig (34 bar)

The Series SF Sight Flow Transmitter is a Series of sight indicators which can display flow or contents of pipelines and provide an analog 4 to 20 mA signal proportional to the flow rate. It is available with a 316 SS or clear polycarbonate cover.

Calibration Option available under Accessories.

Product Applications

Cooling and lubrication circuits
HVAC systems
Aggressive chemical metering
Batching systems

Integrates tangential turbine technology with hermetically sealed circuitry to provideaccurate flow measurement and control in the harshest environments
2-wire loop-powered design transmits a 4 to 20 mA signal proportional to flow rate forremote flow monitoring
Clear polycarbonate viewing cover option for visible indication of flow
316 SS cover offers added protection with pressure limit up to 500 psig (34 bar)
LED power indication, adjustable zero and span, polarity protection and over currentlimiting
Accurately measures flow in both directions and can be mounted in any orientation
